Application filed July 8, 1907.

Specification of Letters Patent.

Potent-ed July 1908.

Serial No. 382,577.

To all whom it M ay concern:

Be it known that I, Ruin. L. SnARrNncK, of Winthrop, in the county ofSutl'olhund State of Massachusetts, have invented eertnin new and usefulImprovements in hollen Bearings; and I hereby declare that thei'ollowing is a full, clear, and exact deseription of the some,reference heing had to the neeompnnying drawings, ilorinii'ig pert ol'this specification.

This invention has reference to roller hen!- ings and particularly tosuch hearings de signed for use in combination with car uxle boxes orsimilar casings.

The ohject ol the invention to so construt-t n roller hearing that theseparator devices for the anti friction rolls shall have rolling eontnctonly with said nnti friction rolls and with the connecting menus of saidseparotor rolls.

Another object of the invention is to reduce the friction on the antifriction rolls, so celled.

Other objects of the invention will nppenr from the followingdescription.

The invention consists in the SO 'Ht'tILlO'l rolls and in the peculiarmeans for supporting the some out of content with the journnled shaltand with-the race way.

The invention also consists in the comhinzn tion with the roller hearingof the peeuliur casing therefor.

The invention also consists in such other peculiar :l'ezttures oiconstruction and cone hinntion of parts us shall hereinafter be morefully described and pointed out in the claims.

Figure 1, represents a seetionnl View ol the improved roller he ring andits easing taken on line 1-1 Fig. 2. Fig. 2, represents it crosssectional View taken on line 2---2 Fig. 1.

Similar numbers oi reference designate corresponding parts throughout.

In carrying this invention into practice I construct a easing, or box,which in its oreferred form has the cylindrical well 5 fun nished on itsexterior with the projections 66, the cross ineinhcr Thriving the ends8-8 and the groove 9. Internally the ensing 5 is furnished with theannular rih l 1 and with the grooves 12. Mounted on the membeer 7 of thecasing 5, is the rocker 13 having the cross sectional shape shown inFig. 1 end furnished on its flat surfaces with the ribs 14 and 15 whichfit respectively, the groove 9 of the member 7, and the similar groove16 of the saddle 17, whereby lateral pressure on said saddle is resistedh the leverage oi the flat. surfaces ol the rocher 13 zigninstthe sur-"zn-es on which they near.

Within thecosing 5 are the nnti friction rolls 2-t-2 t which are free torotnle on their respective nxes and to revolve, or trnvel, in theraceway formed by the inner surl'nce oi the casing, hut longitudinalmovement of which rolls is prevented by the engagement of theiroentrnlly located unnuhir channels .25 with the rib ll of said easing,while. the grooves 2(3'-2ti' in the peripheries oi" said rolls aredesigned to receive portions of the separating rolls. The not: frictionrolls fl-t--- it ore designed to receive and rotni-nhly sup-- port thesh: t A and to freely :otule nnd revolve under the rotattion ol saidshalt. in

rder that said nn'ti friction rolls run innintuin theirrelutivopositions \i ithout exertim; undue i'riotionz'rl resistance thereon, ifride separating deviees for said :rntit'rietion rolls which sepnrntingdevices comprise pairs of rolls 27----28 located hotwoen adjacent pnirsot' anti friction rolls. 'lhe rolls have nnnulur rihs fil -2U, engngedin the grooves l3---l3 oi the rnsiug. nnd the the ribs 2-)---29 with theedger-z ol the grooves i 12 -l; of said casing may oceo When the shoi'tA oper E F-ht will rot-ole nhout their own '1. revolve shout the nxis oithe shntt A, the rolls 2? and .ZR i reason oi their frictional eontnotwith the antir iotion rolls, will rotate independently and revolve withthe rolls 24""24 nnd the rings 3'2 will be rotated by reason oi theirriotional contact with the rolls 27 and 2S and frictional resistnnee tothe rotntion oi the rolls 24- -24 and the shaft A will be practicallyeliminated by the free rotation of all the movin ports in unison.

Hnving thus desori )ed my invention 1 ehiiin as new nnd desire to secureby Letters Patent.

1. A roller hearing comprising neylintilt) annular channels, engagedwith said rib, and

'drioel oesing having an annular rib write in- 1161 surface, a series ofanti friction rolls having annular grooves, a series of pairs of separator rolls, arranged between the anti friction rolls, one of each pair ofthe separator rolls having annular ribs engaged in the annular groovesof the anti friction rolls, and rotatable means engaged with each pairof separator rolls as described.

2. A .roller bearing comprising a cylindrical casing having an annularrib and annular grooves, a series of anti friction rolls within thecasing each having an annular channel, engaged with said rib, and.annular grooves,

eeaeer a series of pairs of separator rolls arranged in pairs betweenthe anti friction rolls one of each pair of which rolls has a reducedportion to clear said rib and apair of annular ribs engaged in thegrooves of the anti friction rolls and of the casing, and a series ofrings each of which embraces a pair of said separator rolls and isfree-t0 rotate and revolve therewith.

In testimony whereof I affix my signature in presence of two witnesses.
